How do I remove desktop and use X and twm

On my 14.04 system,
[code]
 init --> login
   login --> startx
     startx --> xinit
       xinit --> X
       xinit --> xterm (console)
         xterm(console) --> twm
         xterm(console) --> xterm and etc.
[\code]

What do you want to do on the remote system that needs the whole desktop? I bet there is a sleeker solution to what you are try to do.

I do not like the desktop and all its bloat. I do very little where
point and click has any advantage.

I I prefer to operate my computer more console-like. As I said in my
post, I prefer to use X and twm, which I do on 14.04.

There must be some easy way to not start lightdm and get what I want
with startx.

If you use the terminal very little, why not connect to the server via SSH.

What activities do you do on the remote system when you get connected?

A server is not involved. I am concerned with this one desktop system,
with Ubuntu 14.04 on sdb and a testing installation of Ubuntu 16.04 on
sda. The 16.04 on sda is for future upgrade. So far, 14.04 does all I
need, but, its EOL is less than 3 years away. Also, I have some minor
problems with Linux 3 and think there may be some possibility that Linux
4 is better.

More details on my use of the Linux system:
I use several xterms for development and math, pari, octave and maple.
When not in use, the xterms are iconized. I do some cross compiling for
robotics and other electronics. I currently have a couple active coding
projects and three active math problems.

I only use desktop applications for email and browsing.

How do you compile your code? In a terminal?

If you want to Web browse using the other system then you can use an SSH tunnel from the client system to the remote PC then use the tunnel as a Web proxy.

I use an xterm, make, gcc, etc.

This discussion seems to be drifting away from the way I use this
computer. I have a desktop system, running X and twm.

The hardware for my desktop is:
   core i7, OC 4.2GHZ,
   16G RAM, 2x500G disk,
   usb kbd/mouse,
   AMD Radeon 6870.
   Networked with 7 other computers behind a firewall.

I use the keyboard, mouse, and, display attached to that system. I do
use SSH, but, for connecting to target systems, etc.

Since I use X and twm, I can run a web browser. I prefer seamonkey.

Here are the software details of my 14.04 system

   PID PPID STAT TIME COMMAND
  1566 1 Ss+ 00:00:00 /bin/login -f
  1658 1566 S+ 00:00:00 /bin/sh /usr/bin/startx
  1678 1658 S+ 00:00:00 xinit /home/tomdean/.xinitrc -- /usr/bin/X :0
  1679 1678 Rsl+ 00:04:37 /usr/bin/X :0 -auth /tmp/serverauth.VUh4xqgqnU

  1692 1690 S 00:00:05 xclock -digital -twentyfour -update 1

  1876 1693 Ss 00:00:00 bash
  2437 1875 Sl 00:01:18 /usr/local/seamonkey/seamonkey

With the out-of-the-box Ubuntu 16.04 installation, this involves 159
processes, from lightdm through xterms, thunderbird, and, firefox.

Hope this makes my situation clearer.

The answer is very simple.

sudo apt-get remove --purge lightdm
